LOCOMOTIVE.

Application iled February T 0 @ZZ w 7mm it may concern.'

Be it known that '1, lViLLLiM F. KrnsnL, Jr., a citizen of the UnitedStates, and resident of Altoona, county or" Blair, State ofPennsylvania, have invented certain' new and useful Improvements inLocomotives, of which the following is a specification.

rllhe present invention relates to locomotives and more particularly tothe arrangement and disposition of the steam piping for supplying steamto the auxiliaries and steam operated apparatus at the front of thelocomotive. Heretofore this apparatus has been supplied with steam bymeans or pipes disposed on the outside oit the locomotive shell wherethey are subject to considerable condensation. Furthermore in most casesthese pipes extended into the cab adding to the general congestiontherein.

rEhe principal objects of the present-invention are-to eliminate some ofthe piping on the outside of the locomotive extending from the cab tothe iront of the locomotive; to relieve the congestion ofpipesandlvalves inthe cab; to locate the pipingior'supplying steam to theauxiliaries at the front of the boiler, within theshell, that is withinthe boiler and smoke box as far as possible; to provide a :trontbridgepipe having 'a valve disposed within the shell and operable from theexterior thereof and to utilize t-his valve as a substitute for a gussetplate brace.

To the above ends-the invention'comprises a steam pipe, or front bridgepipe, extending from the steam dome-or other source of steam supplythrough the front head of the boiler into the smoke. box, thence throughthe front head of the smoke box and thereafter branched' to supply steamto the turbine, eompressors and other apparatus. 1n the smoke box thesteam pipe is tapped to supply steam to the blower nozzles and smokelifter. lVithinthe boiler the bridge pipe has a valve for controllingthe flow or' steam therein, said valve beingI operable from the outsideof the boiler shell.

@ther objects and features' ofy novelty will be apparent from thedescription taken in connection with .the drawings, in which- Figure lis aside elevation at the front of a locomotive, parts being in section,illustrating the piping andv valves arranged according to the presentinvention;

Figure 2 is a plan view of parts showniin Fig. l, portion of the smokebox shell being broken away.;

from the-steam dome orv other source ofsteam f supply to the valve l1disposed within the boiler shell adjacent thew front fluerl sheetthereof, the pipe l0 also lying within the boiler shell. From the valve1l a pipe l2 eXtendst-oa 'l' 13. From this T a pipe 1i extends throughthe iront` head 15 of the smoke box where it is providedy with abranch-,pipe 16- for/ supplying steam to the head light turbine and witha lubricator 17.

Thereaiter the pipeisbranehed, one-branch 18l supplying steam tothecompound air compressor lil-andthe otherbranch 20 supplying steam toalike compound air coinpressor 2l at theopposite sidey of the locomotive.Theexhaust from the compressor 19 is conducted through a pipe 22,v tothe blower'nozzle casting 23; this casting having a plurality of"yblower nozzles*v 24;, eachk of which discharges into oneof4 a'pluralityof vertical passagesy 35' inthe stack. The opposite compressor 2l hasanvexhaust pipe 26 which extends tol theY opposite end of the nozzlecasting 23.

The T 13 Awithinithe smoke boX'oi tlieflocomotive has a pipe 2T leadingto` a valve 28 f which controls the supply of'steam through pipe 29 tothe nozzle casting. Above the valve 28tlie pipe 2T is tapped to supplysteam\ througlr a pipe 30 to a` smoke lifter valve 3l which controls thesupply oit steam through apipe?J to a smoke lifter at the top of: thestack.

The valve 1li whichI controls`l the supply of steam tothesteanrconsuming apparatus at ther front of the locomotive preferablycomprisesan elongated` body 33 having an `inlet chambervt separated byportedwall Bfrom the outlet chamber-36. .ln addition to the usual inletopeningfor. the inletvr chamber 34. the valve body is alsov providedwith ,an opening for the removable lbonnet 37, a flange h'eingprovidedaround this opening.` Aecordingto the presenti invention this flange issecured to theboiler shellv 39 by rivets 40. Further if desired a leaktight connection may be provided by al weld such as indicated at 41. Thebonnet 37 extends through an opening 42 in the boiler shell whichregisters with the adjacent opening in the body 33 of the valve. Thisbonnet is secured in position in any suitable manner as by means of thestuds 43. A valve stem 44 extendsthrough the bonnet and is carriedthereby, and at its inner end has a projection and slot connection witha valve disk 45 which controls the ports in the wall A suitable stufngbox 4G may be provided around the stem 44. It will be observed that thebonnet 37 together with the valve stem may be removed from the valvefrom the exterior of the boiler, thus giving access to the interior ofthe valve. At its outlet end the valve extends through the front uesheet 47 of the boiler and is rigidly connected thereto, For thispurpose, as shown, the valve body has a flange 48 bearing against theinterior surface of the flue sheet and a nut 49 screwed on the outletend of the valve body on the other side of the flue sheet adapted toclamp the flue sheet against the shoulder when it is screwed up. In thismanner, as the valve body is secured to the boiler shell and Hue sheet,it acts as a gusset plate to hold the Hue sheet against deflection.

It will be observed, according to the present invention, except for thevery short klength in front of the locomotive head, all

the piping for supplying the auxiliaries is disposed Within the boilershell and hence there is practically no condensation of steam thereinaFurthermore, the valves and piping heretofore extending to the cab havebeen eliminated, and yet the supply of steam may be readily controlledbecause of the valve 11 operable from the outside of the boiler shell.

Although a specific arrangement of the piping and a specific valve for.controlling the same have been described in detail, it is to beunderstood that .the invention is not thus limited, but includesmodifications and changes which come within the scope of the appendedclaims. v
